[opnfv-tech-discuss] [Parser] VeriGraph demo (video)

2017-11-03 Thread Serena Spinoso 

Dear all,

I have uploaded a video of an old VeriGraph demo here 
. I 
have thought you may be interested to watch it in view of the next 
online meeting to start in understanding how VeriGraph works.


It is the same demo we prepared for introducing VeriGraph in Parser one 
year ago. In practise, VeriGraph was integrated in an NFV orchestrator, 
Escape, developed in another project and the aim of this demo was to 
show the verification workflow implemented by the overall architecture 
(i.e. Escape + VeriGraph). In fact, the video shows that at the 
beginning I requested a service graph (shown in the jpeg file available 
on the public link) where a firewall was erroneously configured to drop 
any packet. In this case, the verification failed and the deployment of 
the graph was stopped. Then, the video continues by showing the 
deployment of the same service graph but with a correct firewall 
configuration. This second request has been completed because the 
verification succeeded.  In both the service graph requests, VeriGraph 
had checked the reachability of any host of the network with the web server.


As I told you, this is just an example of what we expect VeriGraph can 
do within Parser. We can discuss more in depth about the inputs required 
by our verification service and its outputs, on how the overall 
architecture can manage such information, during the next online meeting.


In case we have time, we may discuss also about the apigateway and its 
API, because I tried to experiment with it, but I have encountered some 
problems.


Many thanks,

   Serena

Re: [opnfv-tech-discuss] Support of new types in TOSCA

2017-10-23 Thread Serena Spinoso 

Hi Xiaodong and Julien,

today we tried to connect but there was no meeting on zoom and gotomeeting.

Can we schedule an on-line meeting in the next days?

Thanks,

   Serena

Hi Xiaodong and Julien,

we plan to participate to the next call on zoom (on Monday 23/10). 
Maybe we can discuss about this new feature during the call.


In the meanwhile, as Xiaodong asked, Verigraph needs a network service 
descriptor containing node types already available in Verigraph's 
catalogue, in order to load the correct function models and run the 
verification process. Currently Verigraph supports some function 
types, like firewall, NAT, endhost, web server, web cache, DPI, etc. 
For each new node, we also need to pass its configuration to 
initialize the function model (e.g. filtering rules for firewall).


Furthermore, since Verigraph checks the reachability between two nodes 
of the network topology, we also need a way to specify what Verigraph 
has to verify on a given network service (we generally name this kind 
of information as "policies)". I notices that TOSCA already provides a 
way to define a set of policies. So it would be useful if we can add a 
new type of policy (e.g. verification policy) in order to pass the 
required inputs to Verigraph.


thanks for your interest and help,

   Serena

I'am sorry missed Serena's email in my office mail, and i cann't find

As julien said, adding tosca in verigraph is great ideal. From the 
Tosca specification point of view, if the basic types(node type, 
relationship type, requirement type, etc.) don't meet the 
requirements, you can optionally add custom types as long as the 
specification constraints can be satisfied, the point is how to use 
the topology(defined with new types) parsed by tosca-parser.


We can discusse it again through email or usring meeting or irc. and 
it will be better for our discussion if you could send your demand 
ahead of schedule.

Hi Serena,

It's a great news for TOSCA supported in Verigraph. It will
make TOSCA template more useful and enhance Parser ecosystem.
Currently Parser is integrating with ONAP project.

If it is reasonable, we can add it in Parser project. Let's
discuss this issue in email or with a meeting.
Xiaodong, can you hold a team meeting using zoom?

Hi Shang, All,

we would like to add the support of TOSCA in Verigraph,
but we noticed
that our catalogue of network functions does not exactly
match with the
types of nodes offered by TOSCA. That is the reason why
we would kindly
ask you how we can add new node types in TOSCA and, in
turn, in Parser.

Thanks a lots.

Re: [opnfv-tech-discuss] 答复: Re:  About parser in OPNFV release E

2017-09-04 Thread Serena Spinoso 

Hi Xiaodong,
yes, we are ready for an update of verigraph. We did many improvements 
and optimizations on Verigraph and we may include them in parser if we 
are still in time. Do you think we can do it, based on the E release 
planning?


For what concerns the Verigraph integration, instead, we do not have 
still clear how the API gateway will interact with the other 
sub-modules. In order to better understand how we can integrate 
Verigraph, I also looked for the other integrations (e.g. the tosca2heat 
integration) in the latest commits, but I did not find so much in the 
api_gateway module (in case I am getting wrong, please let me know). So, 
maybe it would be better to leave the Verigraph integration for the next 
parser release.


I would use this occasion to ask you some clarifications on how we can 
participate to the parser discussions on IRC. We are not so practice 
with the IRC tool and we encounter some issue in logged in the parser 
channel (I tried with my linux foundation credentials).


Many thanks for any your help,

   Serena

Hi Xiaodong,
thank you for your message. Yes, we are willing to provide more
contributions to parser, especially for verigraph integration. The item
about verigraph that is already in the list is good for us.
Apart from it, we were planning some slight maintenance on verigraph
itself, in order to eliminate some of its current dependencies and
simplify it, but I don't know if we need to specify this item in the
planning list.
Do you plan to have online meetings in the next weeks? It would help us
better understand the context for verigraph integration. Today we tried
to connect but there was no meeting on zoom.
Best regards,

Riccardo
